Supervisors Procurement Notes

Verify component availability through authorized distributors as stock status may vary. Confirm RoHS compliance and lead times directly with suppliers. Ensure the specific suffix matches design requirements. Cross-reference datasheet specifications against application needs before finalizing procurement orders to avoid compatibility issues.

Supervisors Selection Notes

Select this part when a fixed 4.38 V threshold is required for voltage supervision. Consider the 125 nA quiescent current for low-power battery applications. Verify that the TDFN-8 package fits the PCB layout constraints. Ensure the manual reset feature aligns with the system's user interface requirements.

Supervisors Part Context

This component belongs to the MAX16058 series of supervisory circuits designed for precise voltage monitoring. It complements other Maxim Integrated PMIC solutions by offering integrated watchdog functionality. The series supports various threshold voltages to accommodate different rail monitoring needs in compact form factors.

Supervisors Replacement Considerations

Consult official documentation for direct pin-to-pin substitutes within the MAX16058 family. Verify threshold voltage compatibility when considering alternative part numbers.
